J/A+AS/123/473      Late-type star spectra (Montes+ 1997)

Description:
    In this  work we  present spectroscopic  observations centered  in the
    spectral lines most widely used as optical indicators of chromospheric
    activity  (H{alpha}, H{beta}, Ca II H & K,  and He I D{3}) in a sample
    of F, G,  K and M  chromospherically inactive stars.  The spectra have
    been obtained with  the  aim  of  providing  a  library  of  high  and
    mid-resolution  spectra to be used in  the application of the spectral
    subtraction  technique to obtain  the active-chromosphere contribution
    to  these lines in  chromospherically active single  and binary stars.
    This  library can also be used for spectral classification purposes. A
    digital version  with all  the spectra  is available  via ftp  and the
    World Wide Web (WWW) in both ASCII and FITS formats
